4. Adjusting Your Road Bike Brakes After Pad Replacement

Why is it important to adjust my brakes after changing the pads?

After replacing your brake pads, it’s crucial to adjust them for optimal performance. Misaligned or improperly adjusted brakes can compromise your safety and reduce braking efficiency.

Centering the Brakes: Ensure that both brake pads contact the rim simultaneously and with equal force. If one pad is closer to the rim than the other, use the centering screw (usually located on the brake caliper) to adjust the brake arms until they are even.
Setting the Pad Clearance: Adjust the distance between the brake pads and the rim. Ideally, there should be a small gap (about 1-2mm) between the pads and the rim when the brake lever is not engaged. This prevents the brakes from rubbing against the rim while riding.
Toe-In Adjustment: “Toe-in” refers to the angle at which the brake pads contact the rim. The front edge of the pad should contact the rim slightly before the rear edge. This helps to reduce brake squeal and improve modulation. You can adjust the toe-in by slightly bending the brake arms or using специальные toe-in pads.
Cable Tension Adjustment: Adjust the cable tension to ensure that the brake lever has the correct amount of travel. The lever should not bottom out against the handlebar before the brakes fully engage. You can adjust the cable tension using the barrel adjuster on the brake lever or the caliper.
Test Your Brakes: After making these adjustments, test your brakes in a safe area to ensure they are working properly. Squeeze the brake lever firmly and check that the brakes engage smoothly and evenly.

According to research from the Motorcycle Safety Foundation (MSF), in July 2025, proper brake maintenance provides safety.
